STARTING AND OPERATING 85
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is designed to reduce fuel
consumption. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal, pressing the accelerator pedal or
shifting out of DRIVE (D) will automatically re-start the engine.
This vehicle has been upgraded with a heavy-duty starter,
enhanced battery, and other upgraded engine parts to
handle the additional engine starts.
AUTOSTOP MODE
The Stop/Start feature is enabled after every normal
customer engine start. At that time, the system will go into
STOP/START READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP ACTIVE.
To Activate Auto STOP/START, The Following Must Occur:
The system must be in STOP/START READY state.
A STOP/START READY message will be displayed in
the instrument cluster within the Stop/Start section
Ú page 67.
The vehicle must be completely stopped.
The gear selector must be in a forward gear and the
brake pedal pressed.
The engine will shut down, the tachometer will move to the
zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained throughout the Auto Stop/Start process.
